Product Introduction

The 3433501023 / 3433500723 Differential Repair Kit is a complete internal repair solution designed for the differential system of Mercedes-Benz and MAN heavy-duty trucks. It is mainly used to repair worn differential internal components such as spider gears, differential shafts, washers, and related rotating parts.

The differential system is responsible for distributing torque between axle shafts while allowing different wheel speeds during vehicle turning. The spider gear set plays a critical role in maintaining smooth differential movement, reducing internal friction, and ensuring stable power transmission.

During long-term heavy-load operation, differential components are exposed to continuous torque, impact loads, gear engagement, and vibration. Wear of spider gears, shafts, or washers may cause excessive clearance, abnormal noise, vibration, uneven power distribution, and reduced drivetrain efficiency.

The 3433501023 / 3433500723 differential repair kit provides an efficient maintenance solution by replacing damaged internal components without replacing the complete differential assembly. The matched components ensure proper installation accuracy and restore original differential operating performance.

Manufactured from high-strength alloy steel with precision forging, CNC machining, and heat treatment processes, the spider gear set offers excellent strength, wear resistance, and fatigue durability. Accurate dimensions ensure correct fitting with differential housings, gears, and shafts.

Designed according to OEM specifications, this repair kit provides reliable replacement compatibility for Mercedes-Benz Actros, Axor, NG, SK, Econic, North Benz, and MAN truck axle systems. It is widely used for differential overhaul, rear axle repair, fleet maintenance, and aftermarket drivetrain repair applications.

Each repair kit undergoes strict quality inspection including dimensional accuracy testing, gear surface inspection, hardness testing, material verification, and assembly compatibility checks to ensure dependable performance and extended service life.
